AWS LightSail Create Terraform

Here’s how to launch a LightSail instance using Terraform. Create a main.tf file.

terraform {
  required_providers {
    aws = {
      version = >= 3.22.0"
      source = "hashicorp/aws"
    }
  }
}
provider "aws" {
  profile = "default"
  region  = "us-east-1"
}
resource "aws_lightsail_instance" "yourinstance" {
  name              = "yourinstance"
  availability_zone = "us-east-1a"
  blueprint_id      = "amazon_linux_2"
  bundle_id         = "nano_2_0"
}

To launch, run the following Terraform commands.

terraform init
terraform apply

AWS EFS Create Terraform

Here’s how to build an EFS file system using Terraform. Create a main.tf file.

terraform {
  required_providers {
    aws = {
      version = ">= 3.22.0"
      source = "hashicorp/aws"
    }
  }
}
provider "aws" {
  profile = "default"
  region  = "us-east-1"
}
resource "aws_efs_file_system" "efs-test" {
   creation_token = "efs-test"
   performance_mode = "generalPurpose"
   throughput_mode = "bursting"
   encrypted = "true"
 tags = {
     Name = "efs-test"
   }
}
resource "aws_efs_mount_target" "efs-mt-example" {
   file_system_id  = aws_efs_file_system.efs-test.id
   subnet_id = "subnet-xxxxxxxxxxxxxxxxx"
   security_groups = ["sg-xxxxxxxxxxxxxxxxxx"]
}

To launch, run terraform.

terraform init
terraform apply

Create Instance With Alias IP

How to create an instance from a snapshot with alias IP and reserved IPs.

#!/bin/bash
gcloud beta compute instances create jump-server \
--network-interface=aliases=10.128.1.0/24,private-network-ip=jump-server,subnet=default \
--machine-type=n1-standard-1 \``
--network-tier=PREMIUM \
--maintenance-policy=MIGRATE \
--service-account=xxxxxxxxxxxxx-compute@developer.gserviceaccount.com \
--tags=int-webserver \
--image=debian-10-buster-v20201216 \
--image-project=debian-cloud \
--boot-disk-size=20GB \
--boot-disk-type=pd-standard \
--boot-disk-device-name=jump-server-1 \
--no-shielded-secure-boot \
--shielded-vtpm \
--shielded-integrity-monitoring \
--labels=name=jump-server \
--reservation-affinity=any \
--zone=us-central1-a \
--project=airy-totality-151318

The default command uses –private-network-ip and –subnet options separately.

--private-network-ip 10.0.0.24 \
--subnet=default \

But when dealing with aliases, reserved IPs and subnets, use a single –network-interface option instead.

--network-interface=aliases=10.128.1.0/24,private-network-ip=jump-server,subnet=default \
